IMPROVEMENT IN COTTON-PRESSES.

Specification Yforming part of Letters Patent No. 150,8 1S, dated May12, 1874 application filed March 21, 1874.

To all whom it may concern:

Be it known that I, BARTLETT W. BROWN, of Galveston, Galveston county,Texas, have invented an Improvement in Cotton-Presses; and I do herebydeclare the following to be a full and correct description of the same,reference being had to the accompanying drawings, in which- Figure 1 isa side view, partly in section; and

Fig. 2 is a cross-sectional view.

My invention relates to that class of presses which are intended to balecotton. or other baleable material; and it consists in the mode ofoperating the plunger, which is as follows: After the plunger has rundown upon the loose cotton placed in the press, (which heretofore neededa man to tread down, but which my heavy plunger in its rapid descentcompletely accomplishes,) the series of pinions uponl suitable shafts,engaging racks upon the plungcrrods, is, operated by a crank or rotarylever; and, secondly, when the above force is entirely exhausted, theapplication of rope and wheel and axleJ tothe rotary lever, by whichmeans one man can exert the force of many; and it further consists inplacing a curved plate on the opposite side of the bale to be bound,which will return the band, and save a hand in binding.

In the drawings, A represents the frame, and A the sides, which fold up,and may be latched fast when the cotton is in process of being pressed,and may be dropped down when it is necessary to have access to thepressed cotton to bind and tie it. B is the plunger, and B theplunger-rod, which has a rack, b, on two sides of it. Upon suitableshafts, near the top of the frame A, are pinions b', engaging the racksb. These pinions b are operated by the gear-wheels c engaging eachother, and the gear-wheels are themselves operated by a pinion, e, uponthe shaft of the driving-wheel l). This driving-wheel has, first, ahandle, u, upon its outside, by which the` plunger B is raisedl to thetop of the frame at the commencement of the operation of pressing; and

it has, secondly, handles upon its periphery,

d by which the plunger is lowered in the iirst stages of its pressing,until this means has exhausted its force upon the cotton in the press.It has, thirdly, a groove, d, in its periphery, into which a rope isplaced, firmly secured therein at one end, the other end fastened uponthe aXis of the windlass fw, which is operated by the crank k. By ythismeans a still greater force can be exerted upon the cot` ton in thepress 5 also, upon the driving-wheel Dis a space for a ba-nd from thedrivin g-wheel of a steanrengine or other motor, by which the wholecottonpress maybe operated, if desired. Upon the bottoni of the plungerB are grooves b, as also upon the door of the betr tom of the frame.Through these grooves the bands are to pass, when they are put aroundthe bale to be bound.

It is usual to have a man on each side of the pressone to put the bandthrough, and another to receive it and return it upon the opposite side5 but I obviate the necessity of a second lnan by hinging to the frame Athe concave plate I) at p. This plate l) is pro vided with partitions s,between two of which the' band is guided, and returned to the person,

who forces it forward until it reaches the saine concave plate, P, forreturning the band, substantially as described.

The above specification of my said invention signed and witnessed, atGalveston, this 16th day of March, A. D. 1874.
